Dry roast the instant oats on a pan for about 5-6 mins or till they get fragrant. Let them cool and grind them into a powder. This is your oats flour.
*You can make this flour and store in an air tight container to avoid doing this step every time.
In a container, add the oats flour, rawa, curd, vegetables, nuts, ginger, green chilly, cumin seeds, curry leaves and salt. Mix them all together. Add water to make a semi-solid consistency.
Let this sit for 10 mins. The batter will thicken slightly as the rava will absorb water.
Add water to get the right consistency of the batter.
Add Eno / fruit salt along with a little water (to active the fruit salt) and mix it evenly. Don’t over mix as that can subside the bubbles.
Pour into the idli molds and steam.
The idli should be ready in about 10 mins. You can check if they are done by inserting a knife in the middle of the idli. If the knife comes out clean it is done.
Use a spoon to remove the idlis. Dip the spoon in water each time you remove the idli to make the process easy.
